WINDOW FRAME AND sAsH.

SPECIFICATION forming part of Letters Patent No. 761,733, dated June *7, 1904,

Application filed July 24, 1903.

To @Zlio-tem r'zvnfry concern: l

Be it known that I, .GUSTAF WAHLsTRoM, a citizen of the United States, residing at Des Moines, in the county of Polk and State of' Iowa, have invented certain new and useful Improvements in Window-Frames and Sashes Therefor, of which the following is a specification. i Y.

My objects are to provide a device of this class having an inner and an outerv sash containing glass with an air-space between them so arranged asto form tight joints-with the window-frame when the sashes are in theirv closed position, and, further, to provide an outer-W-indow-sash capable of moving downwardly below thel window-sill and forming with the window-sill awater-tight joint either when the sash is in its closed or in itsl open position; and my object is, further, in this connection to provide water-tight.packing-strips .to engage the glass of the sashes, so that a water-tight joint is formed with the glass when the sash is at any point throughoutits limit of movement. l

A further object is to provide a windowscreen in the same window-frame capable of sliding downwardly intol the window-frame and so .arranged as to form with the windowframe and the inner sliding sash a tight joint when either in its closed or in its opened position.

My invention consists in certain details in the construction, arrangement, and combination of the various parts of the device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which- Figure 1 shows a vertical sectional View on the indicated line 1 1 of Fig. 2 through the window-frame and sashes and screen. Fig. `2

shows a horizontal sectional view of same on of the outer sliding sash.

Serial No. 166,862. (No model.)

Fig. 6. Fig. 6 shows a horizontal sectional yview of the window-frame, sashes, and screen, illustrating the same modification shown in Figs. 4 and 5 and taken on the indicated line 6 6 of Fig. 4; and Fig. 7 `shows a perspective view of the outer sliding sash used with the preferred form shown in Figs. 1 and 2.

Referring to the accompanying drawings, and particularly .to the preferred form shown in Figs. 1 and 2, I have used the referencenumeral 10 to indicate the top piece of the window-frame. 11 indicates the outer portion of the sill or bottom of the window-frame, and 12 the inner portion of the sill. The numeral 13 indicates the sides of the frame. In this form of my invention the sashesaand screen areintended to slide downwardly, and hence I have provided space in the wall in which the window-frame is placed below the window-frame. "he reference-numeral 14 indicates the outer portion of the hollow wall, and 15 the inner portion, the space between the outer and inner portions being large enough to admit both the sliding sashes and the slidingscreen.

Erected on the inner faces of the sides 13 of the frame are the casings to receive the sides the opposite sides of the frame are exactly alike and each comprises the side pieces 16 and 17, the outer ends thereof being secured tothe part 13, and attached to the inner ends thereof are thev narrow strips 18 and 19, with a space between them of a size to permit a pane of glass to enter between them and freely slide. Secured to the inner face of the part 19 is a strip 20, and a rubber packing-strip 21 is held between the strip 2O and the part 19. This rubber strip projects inwardly into the opening between the parts 18 and 19.

rlhe outer sash, as clearly illustrated in Fig. 7 comprises a top piece composed of a central strip 22 and` two short side strips 23. The sides are indicated by the reference-numeral 24, and a slight space is left between the ends of the parts 23 and the sides 24. The bottom of the sash is indicated by the numeral 25 and the `glass panel by the numeral 26. On the outer face of the bottom of the sash is a strip 27 to hold the glass in the bottom piece and to engage the under surface of the Th esecasings on IOO sill 11 when the sash is elevated, as shown in Fig. 1. The sash is connected with the frame by having its sides 24 slidingly mounted in the space between the parts 16 and 17, with the rubber strips21 engaging the front face of the pane of glass, and the bottom 25 is placed beneath the sill 11, so that the strip 27 engages the under portion ot this sill 11 when the outer sash is at its upper limit, as shown in Fig. 1. Secured to the top ot' the sill 11 is a packing-strip 28 to engage the front of the pane of glass, so that as the sash slides upwardly and downwardly in the windowframe this strip 28 will form a water-tight joint with the pane of glass, and when the front sash is at its downward limit of movement the strip 23 will overlap the strip 28 and form a water-tight joint with said strip 28, as clearly shown by dotted lines in Fig. 1. By this arrangement of parts it is obvious that the outer sash when in its'closed position will form a water-tight joint both with the casing at the sides of the frame-and with the sillA ot' the window-frame, because the packing-strips 21 and 28 will engage the sides and bottom of the panel of glass, and said strips will continue to stand in engagement with the pane of glass throughout its entire movement, and when the outer sash is at its downward limit of movement the overhanging strip 23 will prevent water from entering under said strip 23.

The reference-numeral 29 indicates a pulley above the outer sash, and a rope 30 is attached to the sash and passed over said pulley, said rope being attached to a weight 31 at the outer side of the side pieces 13 of the frame, as shown in Fig. 2. A similar weight is provided on the opposite side, and said weights are designed to counterbalance the weight ot' the outer sash, so that it will be held in any position in which it may be placed.

The second sliding sash is held in place between the strips 16 and the stops 32. This inner sash is composed of sides 33, slidingly mounted between the strips 16 and the stops 32, and the top and bottom ot' the inner sash project forwardly at 34 enough to engage the inner faces ot the front sash, as eleary shown in Fig. 1. This sash is also provided with ropes and pulleys the same as the outer one.

Immediately in the rear of the stops 32 is a screen composed ot' sides 35 and top and bottom pieces 36. These sides slide between the stops 32 and the stops 37 and the parts 36 and are wide enough to engage the rear oi' the top 31101Ll theinner sash, and the bottom 36 is otl a width to engage the bottom of the middle sash and the front of the sill 12, and a screen 38 of the ordinary kind is placed in this frame. This screen is capable ot' sliding vertically and may be held at various points o't' elevation by means of the spring-stop 39 ol: ordinary construction. (Clearly shown in Fig. 2.)

One of the principal objections to windo\ isashes that open by sliding in any direction except upwardly is that when open ed or partly opened rain may enter the window-lrame through the openings in which the sashes slide. This is highly objectiomible, and lor that reason I have provided the structure before described and in use with the lorm ol window-trame and sash just described. lt is obvious that when the sashes are in their closed position, as shown in Fig. 1, then wa-` ter will be prevented from entering through the openings at the bottom ol the frame on account ot' the strip 23, which lirmly engages the glass, and water will be prevented from entering around the sides ot' the sash by means ot' the packing-stri ps 21, which engage the sides of the glass. I'Iowever, the sash may l'reely slide up and down, and when in either its upper or its lower position water will be prevented from entering the opening in the bottom ofthewindow-frame. W'hen the forward sash is at its lower limit ol n'iovenient,then the overhanging strip 23 will give additional protection and water will be prevented lroni entering said opening. One ol the principal objects in providing a double wimlow-lrame of this kind is to exclude cold air, and it is obvious that when the outer sash is in its closed position the same packing-strips will prevent the entrance of cold air. Furthermore, the space between the two panes ol glass is stopped, so that air cannot circulatethrough it when both sashcs are closed by the upper and lower strips ot the inner sash engaging the mating strips ot' the outer sash.

vIn the modilied llorm illustrated in l `i e` 3 I have shown a structure in which each sash is divided into two parts, one olVA which is eapable ot' moving upwardly and the other downwardly. The top window-lrame is provided with a number ot openings wide enough only to allow the glass ol the upper sashes to pass through them, and the bottom ol the window-frame is made exactly like the one illustrated and described in connection with Fig. l of the drawings. ln this modified form the outer sash is composed of two parts. 'lhe upper part hasits frame composed ol a top piece L10, into which the glass L11 is litted, and a bottom composed ol: an inner strip l2 and an outer strip 43, with the glass 41 admitted between said strips t'roin the top and a rubber packing-stri p 4-1 admitted between said strips 42 and 43t'ro1n the bottom and projecting slightly below the bottom. A Vrope 45 is attached to the strip L10 and passes over a pulley 46, so that a weight may be attached to its other end to counterbalance the weight o l the upper sash-section. The lower portion of the outer sash comprises an upper llramepiece 117, into which the glass 13 is litted, and the lower t'raniepiece comprises an inner strip 4:9 and an outer strip 50, with the glass admitted between said strips. The top ol the outer strip 50 engages the under portion ol' lOO IOS

llS

the sill ll'when the lower sash-section is at' its upper limit of movement.

'Ihe side pieces of these sashfsections are arranged the same as in my preferred form just described. Hence it is not necessary to describe them here in detail.v

lower section arranged substantially like the upper and lower vsection of the outer sash. The glass for the upper section of the. sash is .indicated by the reference-numeral 51 and that for the lower section by the referencenumeral 52, the saidupper section being pro-v construction and operation of this modified,

form are substantially the same as in the preferred form before described.

Referring to Figs. 4, 5, and 6 of the drawings, I have shown another modification of my invention, in which the window sashes and screen are arranged ,to slid-e horizontally instead of vertically. Referring to said drawings,I have used the reference-numeral 58 to indicate arectangular window-frame of the ordinary kind except that the bottom piece is provided with a slot 59, through which the glass of the outer sash may slide, and one of the side pieces is provided with aslot 60 for the sampurpose. Atthetopofthewindow-frame are the stops 61, of ordinary construction, to guide the several sashes and screen-frame, and at one side of the window-frame are the stops 62, of ordinary construction, and at the opposite sidethe'sashes pass through the slots 60 into an opening provided in the wall for that purpose, said openinghaving stops 63 at its top and stops 64 at its bottom edge to serve as guides for the sashes and screens. In the bottom of the window-frame 58 and beneath the slot 59 therein is a frame 65 to slidingly support the bottom of the outer sash, and this frame continues under the opening in the side wall provided to receive the sashes, as clearlyindicated in Fig. 5. The frame of the outer sash is indicated bythe reference-n umeral 66 and the glass `by the reference-numeral 67. The said glass passes through the slot 59 in the bottom of the frame and also through the slot 60 at one side of the frame. rIhe lower portion of the sash-frame 66 rests in the frame 65, and a packing-strip 68, resting on top of the bottom part of the frame 58, engages the front of the glass 67 to prevent the entrance of cold air when the sash is in its closed position. The reference-numeral 69 indicates the second sliding sash, which is like the first except that its lower portion rests on top of the bottom portion of the frame 58 and between the stops 70.

In this modiiied form the in-v ner sash is also composed of an upper and` The reference-numeral 71 indicates the screenframe, which 1s an ordinary rectangular frame resting between the stops 6l at its top and the stops 7() at its bottom edge and passing through f one of the slots 60 at the side.

The essential features of my` invention and the one com mon to `both of the modified forms shown are brieiiy .the arrangement of the outer sash,.inv which parts of its frame enter casings having open-ings therein large enough to permit the glass to pass through them, so

,that a tight joint at this pointvis vprovided to -prevent the admission of moisture or cold air.

Another feature which all of the forms have in common is that the lower portionof the outer-sash .frame stands beneath the sill and a packing-strip fixed to the sill engages the glass, thus preventing the entrance of moisture or cold air at the bottomf the sash. c

Having thus described my invention,.what

I claim, and desire to secure by Letters Patent of the United States therefor, is-
